Frequently asked questions
Is this really free?
Yes, completely. toolmonkey converts images with no subscription, no trial, and no catch. It's supported by ads, not fees.
Do my images get uploaded to a server?
No. Conversion runs entirely in your browser using the Canvas API. Your file never touches toolmonkey's servers.
Why convert JPG to PNG?
PNG is a lossless format that supports transparency. It's the right choice for logos, screenshots, graphics with text, and images you plan to edit further without losing quality.
Will the PNG file be larger than the JPG?
Usually, yes. PNG is lossless, so it stores more data than a compressed JPG. If file size is your goal, consider using Image Compressor or PNG to JPG instead.
Is there a file size limit?
Yes. toolmonkey accepts images up to 20 MB. For larger files, consider reducing the resolution before uploading.
